A) Waste from red blood cells B) Live bacteria C) Fibrin threads D) White blood cells and debris from phagocytosisarrow_forwardMelinda was working the day shift in the hematology laboratory. The laboratory’s protocol called for three levels of blood cell controls to be run at the following times: 1) at the beginning of the shift, 2) within each run of patient samples during the day and 3) any times reagents were changed. The mean for the low (abnormal) control for the red blood cell count was given as 2.00 x 10^12/L, the standard deviation was 0.15, and the confidence limit (acceptable control range) was 2.00 x 10^12/L +/- 2sd (or +/- 0.3). The first morning low control result was 2.10 (x 10^12/L). In five subsequent runs, the low control results were 2.16, 2.19, 2.20, 2.22 and 2.25. 1. Do these values represent a shift, a trend, or neither? 2. Should Melinda be concerned about these values? Explain. 3. Does Melinda need to take any action?arrow_forwardThe lab performs a complete blood count with cell differential while the patient is still in the office.

Shortly after the birth of this baby, the newborn was immediately transported to the Neonatal Intensive Care Unit. The doctors informed Trisha that this baby was suffering from hemolytic disease of the newborn. Explain (i) how hemolytic disease of the newborn arose in Trisha’s second child, (ii) how it should have been prevented, and (iii) the mechanism of action of the preventative treatment for this condition.

He tested HIV positive about 3 years ago, but his infection has remained asymptomatic until 2 months prior to admission. Pneumocystis jiroveci (carinii) pneumonia was suspected and confirmed by culture. Laboratory analysis demonstrates a low CD4+ count of 185 cells/ml. HAART treatment with the antiretrovirals azidothymidine (AZT), efavirenz (Sustiva), and ritonavir (Norvir) was started 2 months ago. QUESTIONS: A medical student asks you to draw a picture of the HIV virion and a CD4+ cell, and to explain the mechanism of intracellular infection and the role of reverse transcriptase.
